Question

An object of mass 26.69 kg that canmove only in the
xy-plane is at rest at the origin of
thexy-coordinate system at time t = 0 s.
Constantforces F1 = (1.881, 0, 0) N and
F2= (0, 1.190, 0) N act on the object.
Athird constant force
F3=
(F3x,F3y,
0) acts on the object att = 0 s in addition to the
forcesF1 and
F2.

(a) What must F3x
andF3y be so that the object does
notaccelerate?F3x = NF3y = N

(b) What must F3x
andF3y be so that at t =6.000
s, the object is at positionr = (1.000, 6.000,
0)m?F3x = NF3y = N
